Created attachment 185946 [details] cam iosched: Call cam_iosched_limiter_init() after ios->current is set to the default The attached patch lets cam_iosched_iop_stats_init() call cam_iosched_limiter_init() after ios->current is set to the default. Previously ios->current was set to 0 until the first cam_iosched_cl_maybe_steer() call. Obtained from: ElectroBSD
